The "recommended" settings are 1280x760 running at 59-60 hertz. When I try to scale the resolution beyond that, even one setting, (1920x1080 is what I would ideally use) the hertz drop to 20-30(interlaced), and parts of my screen begin flickering. Is there any known fix/tweak to this other than buying a new monitor? There is no VGA hookup on my TV, if that is a known fix.
The HDTV you bought is 720p not 1080p. The maximum resolution is 1366 x 768 which explains why you are having issues with 1920 x 1080. You will need to buy a 1080p HDTV if you want 1920 x 1080 resolution.
So is there any way to add 1366x768 to the list of options using windows 7? It goes from 1280x720 to 1280x768 (where it begin flickering) with no other option for a slightly bigger resolution x768 while still in wide screen.
Edit: Earlier today when I was exiting SC2 it left my resolution at 1920x1200 without flickering for a few moments before Windows(?) corrected the display to 1280x720.
